Application filed memb r 27,1913. Serial m. s'caiia rods or links connect the hooks or attaching members to a suitable handle for manipu- .lation.

The objects of my improvement are: first, to provide such an obstetrical instrument that can be readily separated and taken apart and packed in an instrument the various parts;- Fig. 6 is a side elevation. .of the handle part; Fig. 7 is an elevation showing the engaging hook; Fig. 8 is an case; second, to provide such an instrument, combining flexibility with provisions for turning the attached part by a manipula- 'tion of the handle and of, moving the whole by pushing or pulling the same without disconnecting the parts. I attained these objects by the structure illustrated in the accompanying drawings in which- Figure l is an elevation of the whole device; Fig. 2 is an elevation showing the flexibility of the joint; Fig. 3 is a similar elevation showing the formation of the joints upon the several parts and showing the means of disconnecting same; Figs. 4; and. 5 are elevations showing the joints of elevation of another form of the engaging hook. Fig. 9 is an end elevation of a double engaging hook shown in Fig. 8, and Fig. 10 1s a cross section of the same hook.

Similar letters refer to similargparts.

throughoutthe several views.

This instrument consists of a handle, a, and the necessary engaging hook, b, or plurality-ofihooks, (Z, together with any nunib'er of links, as c and 0. adapted to engage the handle, a, and the engaging'hook, b in" such manner that the instrument will be flexible between the hook, band handle. a p

and is capable of being thrust forward or pulled backward without disconnecting.

The disconnectingof the parts of the in strumentz-ar'e accomplished bvso forming treme position withthe openings ,of the o nts toward each other they will slip into links with: the handle, ug'that the joints'are- .slightly' opened sothat brought in an eX-j 55,

each other, then 'by turning them slightly.

' they become engaged so as to be flexible but are able to be twisted or pulled back or pushed forward.

The instrument is used in the ordinary manner by taking hold of the engaging hook, 6,01 d, and engaging it in the fetusto be removed, the handle a being operated by the other hand to turn the engaging hook b, or d, as is necessary and to thrust. the

- whole instrumentforward ordraw it backward as the caiamay be. Besides the 'ordi naryhook, b, the. instrument [can "be sup plied with the-double hook d. This"cofisist's' of two'hinged hooks a and y pointing to- Ward each other. When held in the-hand the finger can draw back the link, and'open Y the hook over the fetus to be engaged and then closed upon it without laceratingfthesurrounding tissues, the link, 0, may then be pushed uponthe sides of the hooks which are notched or corrugated to hold the link 0.

What I claim is 1. In an obstetrical instrument, -'an en gaging hook, a manipulating handle and one or more links, theengaging hook;,-han-.

changeable joints.

2". In an obstetrical instrument, a manipulating handle, oneor more links and one or more engaging hooks, said han'dle,-links and engaging hooks having disengaging and interchangeable joints formed thereon.

In anobstetricalinstrument, a manipulating handle, one or more l inks and engaging hooks and a means for locking the engaging hooks into the fetus; the said handle, links and engaging hooks having disengaging and interchangeable joints formed g DANIELE; MILL ER.
